This project is funded by Asian Development Bank (ADB). The project is located in Shaanxi Province, a relatively impoverished region in the interior part of China that is in transition from a predominantly agricultural to a mixed industrial/agrarian economy. It will be part of the national trunk-line freeway (GZ-40)

The project involves the construction of 176 kilometers of a four-lane controlled access toll expressway across a terrain of flat farm land and Loess Plateau with deep gullies. The first phase of the project, an expressway from Yumenkou to Yanliang (in Shaanxi Province) will become the main transportation corridor in the Weinan Prefecture and will be part of the National Trunk Highway System from Inner Mongolia to the Vietnam border. A second phase of the project involved a 4 kilometer bridge over the Yellow River and the extension of the expressway to the northeast through Shaanxi Province to Houma, a distance of 60 kilometers.

The project provides a bank-grade investment study. It includes travel demand analysis, engineering feasibility analysis, land use and economic impact analysis, cost benefit analysis, and environmental assessment. CHS was responsible for the transportation planning analysis for the project, including travel demand forecasting, cost benefit analysis, and transportation management plan.
